An alternator belt is a rubber belt that connects the alternator to the engine crankshaft. In modern vehicles, it typically functions as a serpentine belt, which drives not only the alternator but also other vital systems, including the power steering pump, water pump, and air conditioning compressor. When the alternator belt wears out, it can lead to diminished electrical performance, battery issues, and even overheating if the water pump is affected.

Like any automotive component, the engine accessory drive belt isn't immune to wear and tear. Over time, it can become cracked, frayed, or stretched, which can lead to a range of issues. Common signs of a failing drive belt include squeaking or squealing noises, especially upon startup or acceleration. Another indicator is the vehicle's accessories malfunctioning; for instance, if the power steering becomes heavy or the air conditioning fails to cool effectively, the drive belt may be the culprit.
